composition: Op. 27 No 1, Nocturne in C# minor

FE (→EE1EE2)

..

The lack of slur in FE (→EE1EE2) is most probably the result of an oversight of the engraver. EE3 added a slur probably after GE1.

Slur placement in GE and EE

..

The pianistic context and the analogy with the preceding bar point to the correctness of the notation of GE. The FE version is most probably mistaken, that in EE is likely a revision following the above mentioned analogy.

Correct notation of the rhythm in EE

..

Just like in bars 29-36, in bar 48 of GE the rhythm  is irregularly presented against the triplets. FE also contains such notation, despite the fact that in bars 29-36 the identical rhythm was presented regularly. A similar situation also occurs in the following bars.
